What is a common cause of hematuria in both dogs and cats?

Hematuria, which is the presence of blood in the urine, can occur due to various underlying conditions in both dogs and cats. Coagulopathy refers to a condition where the blood's ability to clot is impaired, leading to an increased risk of bleeding. When an animal has a coagulopathy, it may experience internal bleeding that can manifest as hematuria, particularly if there is an injury to the urinary tract or if bleeding is occurring within the kidneys or bladder.

Conditions leading to coagulopathy can include various diseases or disorders, such as von Willebrand disease or thrombocytopenic conditions. Because of the potential for hemorrhagic events, coagulopathy is a significant cause of hematuria in both species, making this answer particularly relevant.

In contrast, options like Diabetes Mellitus, extreme exercise, and low carb diets are less commonly associated directly with hematuria in both dogs and cats. While extreme exercise may lead to hematuria in some cases due to muscle strain or trauma, it is not as common or specific as coagulopathy, which can cause more pronounced and direct bleeding issues.
